Need help with my Blower motor please.

hey guys. i am coming to the end of my 2JZ-GE swap. ive got it running and driving pretty well. for some reason my blower motor wont turn on now. it worked just fine before my swap.

i am thinking that the power supply may have been routed thru my factory 5m engine harness? and maybe now that i have done a 2j swap i have to wire it up myself? or do you guys think i just blew a fuse?

any help would be appreciated. its an 85 1/2 MX72. with an OBD1 SC300 2jz / W58.

thanks!

so far from what i have found everything has power. i believe that i have isolated the issue to either a bad or missing ground. i touched my test light to one of the grounds for one of the Many relay's for the HVAC system and it hotwired the blower fan. so, its got power where it needs it but i am missing a ground.

anybody have any ideas?
